question no. 1 and 2 only pls disregard the result in the experiment 

TESTS FOR AMINES Materials: Benzene sulfonyl chloride Thermometer Test tubes Test tube holder & rack Cork or parafilm Вeaker Alcohol lamp Chemicals: Litmus paper 10% NaOH solution Aniline (sample A) 2.5M NaOH N-methylaniline (sample B) 4м кон N,N-Dimethylaniline (sample C) 6M HCI Procedure: 1) In a test tube, place 0.3 ml of each sample, 5 mL of 10% NAOH, and 0.4 ml of benzene sulfonyl chloride. Plug the tube with cock stopper and shake the mixture vigorously for 5 minutes. Take note of the result. 2) Test the misture with litmus paper. Make sure that it is alkaline (add few drops of 4M KOH until it becomes so). Let it stand for 10 minutes. Add 6M HCI dropwise while stirring until acidic. Take note of results. 3) If a precipitate is formed, collect it by filtration or decantation. Test for solubility of the precipitate in 3 ml of 2.5M NaOH. Heat to 50 °C. Shake the tube well for 3 minutes. Experimental results: Before adding 6M HCI After adding 6M HCI After adding NaOH Aniline N-methylaniline N,N-dimethylaniline Questions: 1) What is the basis for the identification of the amines in the test? 2) Devise a separation scheme for the mixture containing methanamine, N-methylmethanamine, N,N-dimethylmethanamine, and methanoic acid.
